Abstract
Provided is a hybrid electrolytic capacitor having large capacitance, low ESR, and superior high-frequency characteristics and high-temperature endurance. The hybrid electrolytic capacitoris provided with: a cathodehaving a cathode substratemade of a valve metal, an oxide layerprovided on a surface of the cathode substrate, an inorganic conductive layerprovided on a surface of the oxide layerand including an inorganic conductive material, and an organic conductive layerprovided on a surface of the inorganic conductive layerand including a conductive polymer; an anodehaving an anode substratemade of a valve metal and a dielectric layerprovided on a surface of the anode substrate; and a composite electrolyte layerhaving a solid electrolyte layercontaining conductive polymer particleswhich is provided between and in contact with the organic conductive layerof the cathodeand the dielectric layerof the anode, and an electrolytic solutionfilled between the conductive polymer particlesin the solid electrolyte layer
